    Swapping out a 6.9 for a 4.9EFI

    Seriously considering removing the 6.9 from my 86 supercab and installing 4.9 EFI with an E4OD from a 1996 F150. Possibly the wrong forum if I expect much encouragement. The 6.9 has a C6 behind it with a GV overdrive attached. It all works fairly well but I am getting rather tired of the noise...
